Embedded Server RAID Technology 1-1

Chapter 1 Overview

This manual describes the Intel Embedded Server RAID Technology.This chapter provides an overview of this product and contains thefollowing sections:

Section 1.1, RAID Benefits, page 1-1

Section 1.2, Product Features, page 1-2

The Embedded Server RAID Technology supports four Serial ATA ports,providing a cost-effective way to achieve higher transfer rates andreliability. Embedded Server RAID Technology supports

RAID level 0 data striping for improved performance

RAID level 1 data mirroring for improved data reliability

RAID level 10 data striping and mirroring for high data transfer ratesand data redundancy

1.1 RAID Benefits

RAID has gained popularity because it can improve I/O performance orincreases storage subsystem reliability. RAID 0 provides betterperformance, while RAID 1 provides better reliability through faulttolerance and redundant data storage. RAID 10 combines both stripingand mirroring to provide high data transfer rates and data redundancy.

1.1.1 Improved I/OAlthough hard drive capabilities have improved drastically, actualperformance has improved only three to four times in the last decade.Computing performance has improved over 50 times during the sametime period. RAID 0 and RAID 10 allow you to access several diskssimultaneously.


14/52

1-2 Overview

1.1.2 Increased Reliability

The electromechanical components of a disk subsystem operate moreslowly, require more power, and generate more noise and vibration thanelectronic devices. These factors reduce the reliability of data stored ondisks.

RAID 1 and RAID 10 systems improve data storage reliability and faulttolerance compared to single-drive computers. The additional drive ineach RAID 1 array makes it possible to prevent data loss from a harddrive failure. You can reconstruct missing data from the remaining datadrive to a replacement drive.

Chapter 2 RAID Levels

Intel Embedded Server RAID Technology supports RAID levels 0, 1, and10. These RAID levels are discussed in the following sections:

Section 2.1, RAID 0, page 2-1



2.1 RAID 0

RAID 0 ( Figure 2.1 ) provides disk striping across all configured drives inthe RAID subsystem. RAID 0 does not provide any data redundancy, butdoes offer the best performance of any RAID level. RAID 0 breaks updata into smaller segments, then stripes the data segments across eachdrive in the array as shown in Figure 2.1 . The size of each data segment

is determined by the stripe size parameter, which is set during thecreation of the RAID set.

By breaking up a large file into smaller segments, Embedded ServerRAID Technology can use both IDE ports and drives to read or write thefile faster. This makes RAID 0 ideal for applications that require highbandwidth but do not require fault tolerance.

Uses Provides high data throughput, especially for large files. Anyenvironment that does not require fault tolerance.

Strong Points Provides increased data throughput for large files. No capacityloss penalty for parity.

Weak Points Does not provide fault tolerance. All data lost if any drive fails.

Drives One to two

RAID 1 ( Figure 2.2 ) duplicates all data from one drive to a second drive.RAID 1 provides complete data redundancy, but at the cost of doublingthe required data storage capacity.


Segment 1Segment 3Segment 5


Segment 7 Segment 8

Uses Databases or any other mission critical environment thatrequires fault tolerance.

Strong Points Provides complete data redundancy. RAID 1 is ideal for anyapplication that requires fault tolerance.

Weak Points Requires twice as many hard drives. Performance is impairedduring drive rebuilds.

RAID 10 2-3

2.3 RAID 10

RAID 10 is a combination of RAID 1 and RAID 0. RAID 10 has mirroreddrives. It breaks up data into smaller blocks, then stripes the blocks ofdata to each RAID 1 RAID set. Each RAID 1 RAID set then duplicatesits data to its other drive. The size of each block is determined by thestripe size parameter, which is set during the creation of the RAID set.RAID 10 can sustain one drive failure in each array while maintainingdata integrity.

Figure 2.3 shows a RAID 10 array with four disk drives.


Uses Works best for data storage that must have 100%redundancy of RAID 1 (mirrored arrays) and that also needsthe enhanced I/O performance of RAID 0 (striped arrays).RAID 10 works well for medium-sized databases or anyenvironment that requires a higher degree of fault tolerance

and moderate to medium capacity.Strong Points Provides both high data transfer rates and complete data

redundancy.

Weak Points Requires twice as many drives..

3-2 BIOS Configuration Utility

3.2 Configuration Strategies

You have two choices when creating a RAID array.

Maximizing Fault Tolerance

You can maximize fault tolerance to protect against loss of data byusing mirroring. Use mirror configuration (RAID 1) to attain thisobjective.

Maximizing Logical Drive Performance

You can maximize logical drive performance by using striping. Selectstriping configuration (RAID 0) to attain this objective.

RAID 10 combines both striping and mirroring to provide high datatransfer rates and data redundancy.

3.3 Assigning RAID Levels

Only one RAID level can be assigned to each array. Table 3.1 displaysthe drives required per RAID level.

Press Ctrl-E to run LSI Logic Embedded SATA RAID SetupUtility

Hold down the key while you press . The main menu for theutility displays.

3.5.2 Selecting a Configuration Method

Section 3.5.3, Configuring Physical Arrays and Logical Drives, providesdetailed instructions for using each configuration method.

3.5.3 Configuring Physical Arrays and Logical Drives

This subsection provides instructions for using the Easy Configuration,New Configuration, and View/Add Configuration to configure arrays andlogical drives.

LSI Logic recommends using drives with the same capacity in a specificarray. If you use drives with different capacities in an array, the CU treatsall these drives as if they have the capacity of the smallest drive.

The number of physical drives in a specific array determines the possibleRAID levels that you can implement with the array. RAID 0 requires one

to four physical drives, RAID 1 requires two physical drives, and RAID 10requires four physical drives.
